"The positive actions they have taken set a great example to all employers on how much can be achieved with the right leadership and desire to effect positive change."

Ms Jones welcomed the accolade and said the assembly would continue to create an inclusive culture, "not only for the people who work here but for the people we represent across all Wales' diverse communities".

It is the first time the assembly has topped the Stonewall Workplace Equality Index 10 years since it was first included in the list. It came third in 2016 and fifth in 2017.
